Logic in query

Question

Invoice posting date range must use the following logic for determining the From - To range:
       To date will be today's minus 1 day to determine last full posting date.
       From date will be - determine current month/year based on 'to date' and subtract 13 months then selection first day of that         month/year.
Example: date that report is run on  = 11/17/11
               To date : 11/17/11 minus 1 day = 11/16/11
               From date : Based on To-date, determine MM/YYYY = 11/2011, minus13 months = 10/2010, 10/01/2010
               Therefore - Invoice posting date range = 10/01/2010 to 11/16/2011.
Please fgive the ideas for this.

Hi
You can create an exit variable in BEX and then write logic in I_STEP.
If you want the date range to be populated as per the system's date then write your code in I_STEP = '1'. If you want the date range to be populated as per the date entered by user in selection screen then write your code in I_STEP = '2'.
Assuming that your scenario is the first one, you below logic. This might have minor errors as I haven't checked the code for syntax errors.
IF I_STEP = 1.
CASE I_VNAME.
WHEN 'ZINV_RNG'.  "Exit Variable created in BEX
DATA: v_date_high LIKE SY-DATUM.
DATA: v_date_low LIKE SY-DATUM.
v_date_high = SY-DATUM - 1.
IF v_date_high+4(2) NE '01'.
year = sy-datum+0(4) - 1.
month = sy-datum+4(2) - 1.
day = sy-datum+6(2) - 1.
CONCATENATE year month day INTO v_date_low.
ELSEIF v_date_high+4(2) EQ '01'.
year = sy-datum+0(4) - 2.
month = '12'.
day = sy-datum+6(2) - 1.
CONCATENATE year month day INTO v_date_low.
ENDIF.
L_S_RANGE-SIGN = 'I'.
L_S_RANGE-OPT  = 'EQ'.
L_S_RANGE-LOW = v_date_low.
L_S_RANGE-HIGH = v_date_high.
APPEND L_S_RANGE TO E_T_RANGE.
ENDCASE.
ENDIF.
Hope this helps.
